ACCORDION.

Specification of Letters Patent.

7 Patented Sept. 15, 1908.

Application filed May 22, 1908. Serial No. &34,224.

T all whom it may concern:

'Be it known that I, HANs HOI-INER, a citizen of Germany, residing atNew York city, Manhattan, county and State of New York, have inventednew and useful Improvements in Accordions, of which the following is aspecification.

This invention relates to an accordion pro vided with novel andeffective means for softening or rounding the tone and at the same timeincreasing the power thereof.

In the accompanying drawing: Figure 1 is a face view of an accordionembodying my invention; Fig. 2 an end view thereof Fig. 3 a longitudinalsection through one of the accordion heads on line 33, Fig. 2, and Fig.4 a cross section thereof on line 44, Fig. 2.

Accordion head is provided with a keyboard 11, the keys 12 of whichoperate the valves 18 that control the sound openings 14, as usual. Onhead 10 is mounted a casing forming a sound chamber 15 with whichopenings 14 communicate. This casing or sound box has a front plate madewith a flat section 16 which joins key-board 11. The top plate hasfurther an outwardly bulged section 17 to form an integral semi-tubularhorn. This horn extends along the entire length of sound chamber 15 andgradually increases in width from the treble keys towards the base keys.That side of the horn which is away from the key-board, is extendedrearwardly as at 18 to contact with head 10, after which the top plateis bent at right angles to form a fiat triangular section 19 directlysupported on head 10.

Horn 17 has an upper elbow 20 terminating in a belled mouth 21 thatprojects above and also in front of the instrument, so as not tointerfere with the player.

Chamber 15 is closed at its back by the key-board 11, at its top andbottom by the end plates 22, and at its front by the extended side 18 ofhorn 17.

It will be seen that the sound waves entering chamber 15 will fiow alongflat section 16 thereof towards the bulged section 17. VVithin thisbulged section or horn, the waves will be entrapped and deflectedupwardly, to be emitted through belied mouth 21. In this way the powerof the instrument is increased, while the quality and softness of itstone is improved.

I claim:

1. An accordion provided. with a sound box having a bulged section thatextends along said box, substantially as specified.

2. An accordion having a head, combined with a sound box having anintegral bulged section extending along said box, substantially asspecified.

3. An accordion having a head, combined with a sound box having anintegral bulged section that extends along the box and widens from endto end, substantially as specified.

4. An accordion having a head, combined with a sound box having anintegral bulged and tapering section that is extended into con,- tactwith the head, substantially as specified.

Signed by me at New York city, (Manhattan,) N. Y., this 20th day of May,1908.
